2 Added experimental support for Windows VSS (Volume Shadow Copy Service).
3 The new '--snapshot' argument to 'wimcapture' makes wimlib automatically
4 create and use a temporary VSS snapshot when capturing a WIM image.
6 Implemented setting of Windows-specific XML information, such as
7 architecture, system root, and version details. This information is now
8 automatically set in newly captured WIM images, when appropriate.
10 The progress messages printed by wimlib-imagex while writing WIM files
11 have been slightly tweaked.
13 Added a new '--image-property' option to 'wimcapture', 'wimappend', and
14 'wiminfo'. This option lets you assign values to elements in a WIM
15 file's XML document by name.
17 The wimlib_get_image_property() and wimlib_set_image_property() API
18 functions now support numerically indexed elements.
20 Fixed a bug where, on Windows, wimlib would change the security
21 descriptor of the target directory of an extraction even when the
22 '--no-acls' option was specified.
25 Fixed a bug with libntfs-3g extraction present since v1.8.1. Sometimes,
26 some Microsoft software would not correctly recognize data in the
29 Made some small improvements to the compression algorithms:
30 LZX compression ratio was slightly improved.
31 XPRESS compression ratio and speed was slightly improved.
32 LZMS compression speed was slightly improved.
34 Improved handling of WIM XML data. wimlib no longer drops unrecognized
35 elements when exporting images. In addition, two API functions were
36 added for better access to elements in the XML document:
37 wimlib_get_image_property() and wimlib_set_image_property().
39 Added support for (unsafe) in-place compaction of WIM files.
41 Improved performance of image export by reusing metadata resources
42 instead of always rebuilding and recompressing them.
44 Improved performance of wimlib_update_image() by delaying the update to
45 the WIM's XML document until a write is requested.
47 On Windows, the target of an extraction may now be a reparse point
48 (which will be dereferenced).
50 On Windows, wimlib now correctly restores non-Microsoft reparse points.
51 However, this remains broken in NTFS-3g mode due to a libntfs-3g bug.
53 On Windows, wimlib now has improved performance when archiving files
54 from a filesystem backed by a WIM (a "WIMBoot" setup).
56 Several improvements to System Compression (compact mode) support:
58 wof.sys (or wofadk.sys) is now automatically attached to the
59 target volume if needed.
61 Compact-mode extractions now work correctly with wofadk.sys on
62 older versions of Windows.
64 For compatibility with the Windows bootloader, the requested
65 compression format now is overridden on certain files.
70 This release primarily contains various minor bug fixes and
71 improvements, including:
73 Improved handling of deep directory structures.
75 Fixed a bug where on 32-bit systems, the library could enter an
76 infinite loop if a WIM file was malformed in a specific way.
78 Added a workaround for a case where libntfs-3g may report
79 duplicate streams in an NTFS file.
81 Windows symbolic links and junctions in mounted WIM images are
82 now automatically rewritten to be valid in the mounted location.
84 Reparse point fixes: correctly handle the "ReparseReserved"
85 field, and correctly handle "empty" (data-less) reparse points.
87 On Windows, wimlib now acquires SeManageVolumePrivilege, which
88 is needed to create externally backed files using the
91 Improved validation of filenames.
93 Improved LZMS decompression speed.
95 The configure script now honors alternate pkg-config settings.
97 Links have been updated to point to the new website.
99 In addition, experimental support has been added for compressing
100 extracted files using System Compression on Windows 10. This
101 functionality is available through the new '--compact' option to
102 'wimapply' and 'wimextract' as well as new library flags.
105 Fixed a bug in the LZX decompressor: malicious input data could cause
106 out of bounds writes to memory (since wimlib v1.2.2).
108 The output of the 'wiminfo' command now consolidates various boolean
109 flags (such as "Relative path junction") into a single line.
111 A file can now have both an unnamed data stream ("file contents") and a
112 reparse point stream. Such files can exist as a result of the use of
113 certain Windows features, such as offline storage, including "OneDrive".
114 wimlib will now store and restore both streams on Windows as well as in
115 NTFS-3g mode. Microsoft's WIMGAPI also has this behavior.
117 On Windows, named data streams of encrypted files are no longer stored
118 twice in WIM archives.
120 On Windows, named data streams are now correctly extracted to existing
121 "readonly" directories. Before, an error would be reported.
123 On Windows, it is now possible to do a "WIMBoot mode" extraction with
124 non-standalone WIMs such as delta WIMs.
126 On Windows, when doing an extraction in "WIMBoot mode", files larger
127 than 4 gigabytes are now never extracted as externally backed. This
128 works around a bug in Microsoft's "WOF" driver.
130 The '--enable-verify-compression' configure option has been removed. If
131 you want to verify a WIM file, use the 'wimverify' program.
133 The way the "file count", "directory count", "total bytes", and "hard
134 link bytes" image statistics (stored in the WIM XML data) is calculated
135 has been slightly changed.
137 In mounted WIM images, the disk usage provided for each file (st_blocks)
138 is now the compressed size rather than the uncompressed size.
140 The performance of the NTFS-3g and Windows capture modes has been
143 On UNIX-like systems, symbolic links whose targets contain the backslash
144 character are now handled correctly (losslessly).
147 Improved the LZX compressor. It is now 15-20% faster than before and
148 provides a slightly better compression ratio.
150 Improved the LZMS compressor. It now provides a compression ratio
151 slightly better than WIMGAPI while still being faster and using slightly
154 The compression chunk size in solid resources, e.g. when capturing or
155 exporting a WIM file using the '--solid' option, now defaults to 64 MiB
156 (67108864 bytes) instead of 32 MiB (33554432 bytes). This provides a
157 better compression ratio and is the same value that WIMGAPI uses. The
158 memory usage is less than 50% higher than wimlib v1.7.4 and is slightly
159 lower than WIMGAPI's memory usage, but if it is too much, it is still
160 possible to choose a lower value, e.g. with the '--solid-chunk-size'
161 option to wimlib-imagex.
163 The '--chunk-size' and '--solid-chunk-size' options to wimlib-imagex now
164 accept the 'K', 'M', and 'G' suffixes.
166 Files are now sorted by name extension when creating a solid WIM file.
168 Fixed various issues related to capture/apply of EFS-encrypted files on
171 The file list printed by 'wimdir' is now sorted by the platform-specific
172 case sensitivity setting, rather than always case sensitively. This
173 also affects the library function wimlib_iterate_dir_tree().
175 On Windows, some error and warning messages have been improved.
178 The Windows binary distribution no longer contains third party DLLs.
179 These dependencies are instead compiled directly into the libwim DLL.
181 Added more fixes for wimlib on non-x86 architectures such as ARM.
183 Extracting files to a Windows PE in-memory filesystem no longer fails if
184 the target files do not yet exist.
186 Improved the performance of XPRESS compression and LZMS decompression.
188 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
189 It will automatically be faster on newer Intel and AMD processors.
191 Removed the --with-imagex-progname and --enable-more-assertions
195 Fix for very slow export from solid WIM / ESD files.
197 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
199 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
200 may use this to treat some types of errors as non-fatal.
202 The library now permits making in-memory changes to a WIMStruct backed
203 by a read-only WIM file.
205 Fixes for "WIMBoot" extraction mode (Windows only):
207 When not using the WOF driver, extraction no longer fails if the
208 disk containing the WIM file has too many partitions.
210 When matching patterns in [PrepopulateList], all hard links of
211 each file are now considered.
213 The system registry files are now automatically treated as being
214 in [PrepopulateList].
216 Added a hack to try to work around an intermittent bug in
217 Microsoft's WOF (Windows Overlay Filesystem) driver.
220 Made more improvements to the XPRESS, LZX, and LZMS compressors.
222 A number of improvements to the Windows port:
224 Fixes for setting short filenames.
226 Faster "WIMBoot" extraction.
228 Updated and slimmed down the dependent DLLs.
230 ACL inheritence bits are now restored.
232 Mandatory integrity labels are now backed up and restored.
234 Added a workaround for an issue where in rare cases, wimlib could create
235 a compressed data stream that could not be read correctly by Windows
236 after an extraction in "WIMBoot" mode.
239 Added file count progress data for
240 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
241 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
243 Added support for testing file exclusions via the user-provided
246 Some documentation improvements.
248 Made some clarifications to the license text in the COPYING file.
251 Made more improvements to the XPRESS, LZX, and LZMS compressors.
253 The default compression mode for wimcapture is now LZX compression in
254 its default mode, which is the same as '--compress=maximum'.
256 You can now specify an optional integer compression level to the
257 '--compress' option; e.g. '--compress=lzx:75'.
259 Made a minor change to the LZMS compressor and decompressor to fix an
260 incompatibility with the Microsoft implementation. In the unlikely
261 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
262 earlier and a checksum error is reported when extracting files from it
263 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
266 Added 'verify' subcommand to wimlib-imagex.
268 Notable library changes:
270 Custom compressor parameters have been removed from the library
271 in favor of the simpler level-based API.
273 Decompressor parameters have been removed entirely.
275 Library users can now specify a custom file for warning and
276 error messages to be sent to, rather than the default of
279 New progress messages:
280 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
281 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
283 New function: wimlib_verify_wim().
286 Improved compression, decompression, and extraction performance.
288 Improved compatibility with version 3584 WIM / ESD files:
289 - Add support for reading and writing multiple solid blocks per
290 archive, which WIMGAPI/DISM can create when appending an image.
291 - Correctly create solid blocks larger than 4 GiB.
293 'add' commands passed to wimupdate will now replace existing
294 nondirectory files by default. Use the --no-replace option to get the
297 The license for the library now contains an exception that allows using
298 it under the LGPL. See the COPYING file for details.
300 In reparse-point fixup mode (the default for capture), symbolic links
301 and junctions that point outside the tree being captured are no longer
302 excluded from capture.
304 Added support for "WIMBoot" capture and extraction. See the
305 documentation for the new '--wimboot' option to wimcapture and wimapply
306 for more information.
308 On UNIX-like systems, you can now backup and restore device nodes, named
309 pipes, and sockets. In addition, 32-bit user and group IDs are now
312 The way that UNIX data is stored in WIM files has been changed. If you
313 captured any WIMs with the --unix-data option, to upgrade them you'll
314 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
315 re-capture them with --unix-data using this version.
317 wimlib now understands tagged metadata items, such as object IDs, that
318 can be stored in WIM directory entries.
320 Removed the --hardlink and --symlink options to wimapply, since I don't
321 think they are too useful and they got in the way of improving the code.
323 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
325 The 'mkwinpeimg' script now supports writing the ISO image to standard
328 The <ARCH> element in WIM XML data is now exported correctly.
330 On Windows, sparse file attributes are no longer set on extracted files.
331 Oddly enough, this actually saves disk space in some cases.
333 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
334 supported. Mounting WIM images now always requires extended attribute
335 support. Use --without-fuse to disable support for mounting WIM images;
336 this will also disable the need for extended attribute support.
338 Configuring with --enable-ssse3-sha1 now works correctly.
340 The shared library version has been bumped up. The main
341 incompatibilities are:
343 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
344 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
347 - User-provided progress functions are now registered using a
348 separate function, wimlib_register_progress_function(). The
349 'progress_func' argument to many functions no longer exists.
351 - The return value from user-provided progress functions is now
354 - A context argument has been added to the prototype of
355 user-provided progress functions.
357 - 'struct wimlib_capture_config' has been removed. The library
358 now takes the path to the configuration file directly. This
359 affects wimlib_add_image(), wimlib_add_image_multisource(),
360 and wimlib_update_image(). However, a NULL value passed in
361 the argument retains the same meaning.
363 - Removed deprecated functions: some (de)compression functions,
364 wimlib_extract_files(), and wimlib_print_metadata().
366 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
367 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
368 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
370 - Removed some progress messages:
371 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
372 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
373 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
376 - Removed some error codes. Numbering stays the same.
378 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
379 WIMLIB_UNMOUNT_FLAG_FORCE.
381 - WIM paths passed to progress functions now have a leading
385 Case-insensitive comparisons of strings (e.g. filenames) containing
386 UTF-16 codepoints above 32767 are now done correctly.
388 Fixed build failure on Mac OS X.
390 wimunmount now provides the '--new-image' option to cause changes to a
391 read-write mounted image to be committed as a new image rather than as
392 an update of the mounted image. (The corresponding new library flag is
393 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
395 The LZMS ("recovery") compression chunk size, or "dictionary size", may
396 now be up to 1 GiB (1,073,741,824 bytes).
398 The performance of LZX ("maximum") and LZMS ("recovery") compression
399 with large chunk sizes has been slightly improved.
402 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
403 decompressed correctly.
405 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
406 occurred in an unlikely case, and due to validity checks it did not
407 affect successfully created archives.
409 Fixed a minor compatibility issue with the LZMS compressor and
410 decompressor. This is *not* the default compression type and was only
411 introduced in v1.6.0. In the unlikely event that you created an
412 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
413 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
416 Memory usage for LZMS and LZX compression has been decreased.
418 wimextract now allows wildcard characters in paths specified on the
419 command line. Also, the '--strict-wildcards' option has been removed
420 and replaced with the inverse option '--nullglob'. See the
421 documentation for wimextract for more details and changes.
423 The wimlib_extract_files() function is now considered deprecated in
424 favor of wimlib_extract_paths().
426 Fixed more permissions problems when extracting files on Windows.
428 A new '--no-attributes' option has been added to wimapply and
429 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
431 The default chunk size is now set correctly when changing the
432 compression type of a WIM, for example with 'wimoptimize'.
434 The '--metadata' option to wiminfo has been replaced with the
435 '--detailed' option to wimdir.
437 In relevant wimlib-imagex commands, '--solid' may now be used as an
438 alias for '--pack-streams'.
441 Support for extracting and updating the new version 3584 WIMs has been
442 added. These WIMs typically pack many streams ("files") together into a
443 single compressed resource, thereby saving space. This degrades the
444 performance of random access (such as that which occurs on a mounted
445 image), but optimizations have been implemented for extraction. These
446 new WIM files also typically use a new compression format (LZMS), which
447 is similar to LZMA and can offer a better compression ratio than LZX.
448 These new WIM files can be created using `wimcapture' with
449 the '--compress=lzms --pack-streams' options. Note: this new WIM format
450 is used by the Windows 8 web downloader, but important segments of the
451 raw '.esd' files are encrypted, so wimlib will not be able to extract
452 such files until they are first decrypted.
454 wimlib now supports extracting files and directories from a WIM image
455 based on a "listfile" that itself contains the list of paths to extract.
456 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
457 and for the library itself, the new APIs are wimlib_extract_pathlist()
458 and wimlib_extract_paths(). Path globs containing wildcard characters
461 For searching WIM files, wimlib now has configurable case sensitivity.
462 The default on Windows is still case-insensitive and the default on
463 UNIX-like systems is still case-sensitive, but this can be overridden
464 on either platform through flags to wimlib_global_init(). For
465 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
466 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
469 Support for compression chunk sizes greater than the default of 32768
470 bytes has been added. A larger chunk size typically results in a better
471 compression ratio. However, the MS implementation is seemingly not
472 compatible with all chunk sizes, especially for LZX compression, so the
473 defaults remain unchanged, with the exception of the new LZMS-compressed
474 WIMs, which use a larger chunk size by default.
476 The compression/decompression API exported by wimlib has been changed.
477 Now one set of functions handles all supported compression formats.
479 `wimcapture' and `wimappend' will now display the progress of scanning
480 the directory tree to capture, in addition to the progress of writing
481 data to the WIM. The '--verbose' option no longer does anything. The
482 library API change for this is the addition of several members to
483 `struct wimlib_progress_info_scan' available to progress callbacks.
485 `mkwinpeimg' now correctly handles the '--start-script' option when the
486 start script is not in the working directory.
488 Sequential extraction, previously requested by using
489 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
490 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
491 behavior (extract in file order).
494 The new LZX compressor added in v1.5.2 has been improved and is now
495 enabled by default, except when `wimcapture' or `wimappend' is run
496 *without* the '--compress' option, in which case the faster LZX
497 compressor is used (the same as before). This behavior is reasonably
498 consistent with ImageX which actually uses "fast" (XPRESS) compression
499 by default. In those cases, use '--compress=maximum' to explicitly
500 capture a WIM image using the new (slower but better) LZX compressor.
502 The '--compress-slow' option still exists to `wimlib-imagex optimize',
503 but its new behavior is to tweak the new LZX compressor even more to
504 produce an even better compression ratio at the cost of more time spent
507 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
508 which recompresses the WIM file using the specified compression TYPE.
509 The new library API function used for this is
510 wimlib_set_output_compression_type().
512 Added the wimlib_get_xml_data() function to allow library clients to
513 easily retrieve the raw XML data from a WIM file if needed.
515 Fixed a bug that could cause an error code to be incorrectly returned
516 when writing XML data containing a <WINDOWS> element.
518 Mounted WIM images will now correctly show the default file stream even
519 if appears in the alternate data stream entries of the corresponding WIM
523 Added a new experimental LZX compressor which can be enabled by passing
524 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
525 optimize'. (The latter is only applicable if the WIM is already
526 LZX-compressed and the '--recompress' option is also given.) The
527 experimental compressor is much slower but compresses the data slightly
528 more --- currently usually to within a fraction of a percent of the
529 results from WIMGAPI/ImageX.
531 A workaround has been added for compatibility with versions of WinPE
532 that interpret alternate data stream entries in the boot WIM
535 An alignment bug that caused a crash in the LZX decompressor on some
538 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
539 the WIM header when restoring the previous state of a WIM it failed to
542 Added a workaround to avoid an access denied error on Windows when
543 replacing a WIM file that another process has opened.
546 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
547 needed to be handled.
549 A bug in the interpretation of negative IMAGE indices in the
550 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
551 `wimlib-imagex append' has been fixed.
553 A workaround has been added to successfully apply security descriptors
554 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
555 2013.1.13 or earlier.
557 `wimlib-imagex capture' can now accept the '--delta-from' option
561 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
562 to standard output and applying images from standard input, but they are
563 not compatible with Microsoft's software and are not created by default.
564 See the documentation for --pipable flag of `wimlib-imagex capture' for
567 To better support incremental backups, added support for declaring an
568 image as a modified form of another image. See the documentation for
569 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
572 Added supported for "delta" WIMs. See the documentation for the
573 '--delta-from' option of `wimlib-imagex capture'.
575 The library support for managing split WIMs has been changed to support
576 other arrangements, such as delta WIMs, and be easier to use. This
577 change is visible in `wimlib-imagex', which also can now accept the
578 '--ref' option multiple times, and also now supports "delta" WIMs as
581 wimlib now preserves WIM integrity tables by default, even if
582 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
583 behavior of `wimlib-imagex' whenever the WIM being operated on contains
584 an integrity table and the '--check' option is not specified.
586 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
587 (when --compress is not specified). This provides the best compression
588 ratio by default, which is usually what is desired, at a cost of some
591 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
592 is the command as in `wimlib-imagex COMMAND'; for example, it can be
593 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
594 appropriate hard links are created in UNIX installations of
595 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
596 batch files that emulate this behavior are generated.
598 Security descriptors are now extracted correctly on Windows.
600 Fixed archiving DOS names in NTFS-3g capture mode.
602 The extraction code has been rewritten and it will now be easier to
603 support new features on all supported backends (currently Win32, UNIX,
604 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
605 now supported on all backends, not just UNIX.
607 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
608 than the WAIK itself.
610 wimlib_global_init() now, by default, attempts to acquire additional
611 privileges on Windows, so library clients need not do this.
613 This update bumps the shared library version number up to 9, since it is
614 not binary compatibible with previous releases.
617 Fixed bug in `wimlib-imagex export' that made it impossible to export an
618 image from a WIM that is readonly at the filesystem level.
620 Return error code rather than segfaulting when trying to list files from
621 a non-first part of a split WIM.
623 Joining a WIM will now preserve the RP_FIX and READONLY flags.
626 On Windows, paths given to wimlib-imagex are now treated case
629 Improved behavior regarding invalid filenames; in particular, on
630 Windows, wimlib-imagex will, when extracting, now omit (with an option
631 to override this default) filenames differing only in case, or filenames
632 containing characters not valid on Windows.
634 On Windows, wimlib now supports capturing and extracting long paths
635 (longer than the so-called MAX_PATH).
637 On Windows, `wimlib-imagex update' now acquires proper privileges when
638 running as an Administrator.
640 `wimlib-imagex update' will now complain if no image is specified when
641 trying to update a multi-image WIM.
643 `wimlib-imagex update' now supports specifying a single update command
644 directly on the command line using the --command option.
646 wimlib-imagex will now choose different units for progress messages,
647 depending on the amount of data that needs to be processed.
649 `wimlib-imagex append' will now generate a unique WIM image name if no
650 name is specified and the defaulted name already exists in the WIM.
652 wimlib now allows you to create unnamed WIM images, which can then only
653 be referred to by index.
655 wimlib now allows you to explicitly declare you want write access to a
656 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
659 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
662 Progress callbacks have been added to wimlib's wimlib_update_image()
665 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
666 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
669 NTFS-3g capture now only warns about two conditions previously treated
672 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
675 wimlib now correctly detects and returns an error when reading a WIM
676 image with a cyclic directory structure. (Fun fact: such a WIM will
677 crash Microsoft's software.)
680 Added new "extract" and "update" subcommands to wimlib-imagex, along
681 with associated APIs in the library. These commands are intended mainly
682 for Windows use but can be used on UNIX as well.
684 Many documentation improvements.
686 Fixed a bug in the Windows build where relative symbolic links were not
687 captured in reparse-point fixup mode.
689 Fixed a bug in the Windows build where file handles were left open to
690 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
692 Fixed a bug in the Windows build of wimlib-imagex where globbing
693 split-WIM parts could cause the program to crash.
695 Fixed a bug where the creation time of WIM images would be shown instead
696 of the last modification time.
698 With the Windows build it is now possible to restore a WIM containing
699 symbolic links as a non-Administrator; however you will receive warnings
700 about not being able to extract the symbolic links.
703 Capturing a WIM image should now be significantly faster in most cases
704 due to improved use of the operating system's cache and avoiding reading
705 files twice whenever possible.
707 The Windows build should now work on Windows XP.
709 The Windows build now supports capturing and restoring hidden,
710 compressed, sparse, and encrypted files.
712 The Windows build now supports capturing and applying WIM images from
713 filesystems other than NTFS (with some reduced functionality).
715 The Windows build now extracts short names correctly.
717 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
718 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
719 capture' and `wimlib-imagex apply'.
721 The performance of splitting and joining WIMs should be slightly
724 The LZX and XPRESS compression and decompression functions are now
725 exported from the library.
728 Improvements and bugfixes for the Windows build.
730 Added --strict-acls options.
732 Fixed the way that wimlib determines the order of images in the WIM.
735 Since wimlib can now be used on Windows, wimlib's implementation of
736 ImageX has been renamed to wimlib-imagex to avoid confusion with
737 Microsoft's implementation of ImageX, which would have the same file
738 name ("imagex.exe"). If you really don't like this you can pass the
739 --with-imagex-progname option to `configure' to choose a different name,
740 or even simply rename the binary yourself (but the former way will
741 configure the man pages to use the chosen name).
743 Various bugs fixed in the Windows build. Mainly to do with capturing
744 and restoring alternate data streams correctly in weird cases, and
745 requesting the correct privileges when opening files. Also added the
746 --noacls options to wimlib-imagex capture, append, and apply.
748 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
749 dynamically loaded, so this may make the library compatible with Windows
750 XP (however, there may still be other problems).
753 Added experimental support for native Windows builds. Binaries can be
754 downloaded from the SourceForge page.
756 --source-list option added to `imagex capture' and `imagex append'.
758 Better support for different character encodings.
761 Storing UNIX file owners, groups, and modes in WIM images is now
762 possible using `imagex capture' with the --unix-data flag.
764 Minor bug fixes and documentation fixes.
767 NTFS capture: Fixed capturing duplicate reparse points.
769 NTFS capture: Capture first unnamed stream if there are more than one
770 (print warning instead of error).
772 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
775 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
778 Update to work with ntfs-3g version 2013.1.13.
781 Fixed truncating file to shorter but non-zero length on read-write
784 Various code cleanups and minor documentation fixes.
787 LZX and XPRESS decompression have received some additional optimizations
788 and should now be even faster. (Although, they were already pretty
789 fast--- much faster than typical I/O speeds.)
791 Fixed a bug introduced in v1.2.1 that would cause a directory tree
792 containing hard links to be captured incorrectly in some cases.
795 By default, unmounting a read-write mounted WIM with 'imagex unmount
796 --commit' will now change the WIM in-place without needing to write the
797 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
800 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
801 for a response from the daemon servicing the mounted WIM. Instead,
802 every second 'imagex unmount' will check if the daemon is still alive,
803 and keep waiting if so, otherwise terminate with an error.
805 'imagex unmount --commit' on a read-write mounted WIM will now print
806 progress information regarding the writing of new or modified streams
807 the WIM, just like when capturing or appending a WIM.
809 A small change has been made to XPRESS compression and it should improve
810 the compression ratio slightly.
812 A change was made that may improve performance slightly when applying a
813 WIM image to a NTFS volume.
815 Microsoft has managed to introduce even more bugs into their software,
816 and now the WIMs for Windows 8 have incorrect (too low) reference counts
817 for some streams. This is unsafe because such streams can be removed
818 when they are in actuality still referenced in the WIM (perhaps by a
819 different image). wimlib will now work around this problem by fixing
820 the stream reference counts. This is only done when wimlib_delete_image() is
821 called ('imagex delete') or when wimlib_mount_image() is called with
822 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
823 requires reading the metadata for all images in the WIM, so this will
824 make these operations noticably slower on WIMs with multiple images.
826 Various other bugfixes.
829 Appending images to a WIM is now be done by default without re-building
830 the whole WIM. Use the --rebuild flag to get the old behavior (which
831 was to re-build the entire WIM when a new image is appended).
833 A new command `imagex optimize' is now available to manually re-build a
834 WIM that has wasted space due to repeated appends.
836 Progress information has been improved, and now arbitrary callback
837 functions can be used to show the progress of a WIM operation.
839 A possible bug with changing the bootable image of a WIM was fixed.
841 Some advisory locking is now done to prevent two processes from
842 modifying a WIM at the same time (but only in some cases). For example,
843 you cannot mount two images from a WIM read-write at the same time.
845 Some functions have been reorganized:
846 * wimlib_mount() renamed to wimlib_mount_image().
847 * wimlib_unmount() renamed to wimlib_unmount_image().
848 * wimlib_overwrite_xml_and_header() removed as
849 wimlib_overwrite() suffices now.
850 * wimlib_apply_image_to_ntfs_volume() removed as
851 wimlib_extract_image() suffices now.
852 * wimlib_add_image_from_ntfs_volume() removed as
853 * wimlib_add_image() suffices now.
855 Previously, the soname of libwim.so has been 0.0.0, despite many
856 interface changes. The soname is now updated to 1.0.0 and will now be
857 updated each release.
860 Resources will now be compressed using multiple threads by default.
861 (This applies to `imagex capture', `imagex append', and `imagex
864 Some performance improvements in mounted WIMs.
866 More progress information is shown when capturing a WIM.
869 Lots of minor fixes, code cleanups, and some documentation updates.
870 Nothing in particular is really noteworthy.
873 LZX and XPRESS compression improvements.
875 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
876 Link Bytes of the WIM.
879 Fixed bug when capturing NTFS file with multiple named data streams.
881 Internally, we are now using inode structures, even though these don't
882 appear literally in the WIM file. This simplifies some of the code
883 (mainly for WIM mounting) and likely fixed a few problems, although it
887 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
891 Enough changes to call it version 1.0.0!
893 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
894 to a NTFS volume, is now supported.
896 Hard links and symbolic links have much improved support. They are
897 supported for WIM capture, WIM application, and mounted WIMs (you can
898 even make them on read-write mounted WIMs).
900 Alternate data streams are now supported on mounted WIMs through an
901 xattr or a Windows-style stream interface. Also they are supported when
902 capturing a WIM from NTFS or applying a WIM to NTFS.
904 Split WIMs are better supported. You may now apply an image directly
905 from a split WIM, mount an image from a split WIM read-only, or export
906 an image from a split WIM.
908 Using a capture configuration file is now supported (but not fully yet).
910 SHA1 message digests are checked in more places, so we can make sure
911 applied and captured data is correct.
913 Man pages have been updated and consolidated.
916 Fixed segfault when unmounting read-only WIM.
919 Support for joining and splitting WIMs.
920 Also, security data is now preserved by default.
923 Can now build with older gcc and system headers, like on CentOS 5.
926 Fixed bug that made it impossible to overwrite files in read-write
930 Write byte-order mark before WIM XML data. (imagex.exe requires this to
